Femora, tibiaj and tarso-metatarsi of a Dinomis of the height of 

 the Din. ingens, but of more robust proportions, from the Middle 

 Island ; with a feeble indication of a surface for a back-toe. 



The tibijB and tarso-metatarsi of Dinomis (Palaptert/x) dromioides 

 from the North Island, confirming by their long and slender propor- 

 tions the conjecture hazarded in the author's former memoir (Zool. 

 Trans. vol. iii. pp. 252, 264). The tarso-metatarsus also shows the 

 rough elliptical surface for the attachment of the back-toe, indicating 

 the Din. dromioides to belong to the šame generic or subgeneric sec- 

 tion as Din. ingens from the North Island. 



Femora, tibice and tarso-metatarsi, from the Middle Island, were 

 next exhibited and described, which establish a new species, for 

 which Prof. Owen proposed the name of Din. casuarinus : a small 

 and feeble depression, five lines by three lines, indicates that this 

 epecies had a back-toe in the corresponding position \vith that in the 

 Apteryx, but more rudimentai. 



A very remarkable femur and tarso-metatarsal bone, also from 

 the Middle Island, ^vere exhibited, belonging to an additional tri- 

 dactyle species, to which the name of Dinomis crassus ^vas given. 

 Of this species the author remarks : " With a stature nearly equal to 

 that of the Ostrich, the femur and tarso-metatarsus present double 

 the thickness in proportion to their length. It mušt have been the 

 strongest and most robust of birds, and the best representative of 

 the pachydermal type in the feathered class." 



The third ne\v species is comparatively a small one, being inter- 

 mediate in size between the Dinomis didiformis and the Din. otidi- 

 formis ; it \vas founded on remains exclusively from the North Island, 

 and was called by the author Dinomis curtus. 



The author expressed his grateful acknowledgments to the follow- 

 ing gentlemen, to whom he was indebted for the opportunity of

The paper (which was illustrated by numerous figures) concluded 

 by some general comparisons and remarks on the geographical 

 distribution of the different species of Dinomis, and with the fol-
